The criminal defense lawyers will not want to have their guys sue, because to do would open them to cross-examination. But that only applies to those that have been charged.
The BEST guys to sue her are the ones who haven't been charged and are in the clear. They can sue her with no reservation, and the charged players can decline to testify until the criminal case is over.
In other words, if this happened, the plaintiffs would be players other than the three defendants. Slander has a one year statute of limitations in some jurisdiction, so by next February, they'd be needing to file their cases, anyway.
Your second paragraph makes sense. I wonder if the fourth player that she identified in the lineup might be the best one to go after her. She clearly stated he was one of her attackers but the police conviently ignored what she said.
